DOOR-HANGER.

To all when: it may concern:

Be it known that I, HERMANN TATJE, a

citizen'of the United States, and a resident 1 of the city of New York, borough of Brook ize it that it may be assembled and taken apart with the least amount of difiiculty and loss of time.

The invention consists .in thenovel construction and combination of partshereinafter described and further pointed out in the claims. In the drawing, forming part of this specification: Figure -1 is a sectional elevat1on of the hanger and supporting rail on-the line 11 of Fig 2,-looking .in the direction of the-.arro'w's; and Ei'gr2 is an end. elevation,

partly in section, the section being taken on the line 2-2 of Fig. 1, looking in the direction of the arrows. Similar reference characters indicate cor respondingjpa'rts throughout the several views.

In the drawin the hanger 1 is shown as being construct out of a single strlp of flat metal comprising) the side pieces 2, top

cross-piece 3 prefera 1y curved at the top,

andlower inturned ends 4, 5, one end lying over the other and provided with holes 6 for the passage of screws. This method of forming the hanger-frameincreases its strength at this point and gives it a long bearing for the purpose of enabling it to be very rlgidly secured to a door 7. v The method of bending one end of the frame over the other is shown in dotted lines. As both flanges are provided with holes, a screw' can be passed therethrou h for the pur ose of readily securing the anger to the cor 7,.

At 8 is shown the run-way or rail grooved at the top to receive the circular tread of the supporting wheel 9. This wheel or roller is mounted on separate sets or runs oi alls, so that the supporting wheel or roller will have a double bearing on the anti-friction balls specification of Letters Patent.

of the wheel; and the anti-friction balls are so supported that they will have abearing in their respective races which is wider than the width of their bearing against the wheel, the anti-friction ballsv being retained iiiindependent races or bearings and rigidly confined in place against inadvertent lateral movement. Thus the supporting wheel is confined in place, its alinement with the supporting rail maintained and lateral displacement relative to the balls and their races or bearings prevented. To secure these results, as Well as to accomplish the other objectsof my invention, I provide separate and independent race-ways or bearings 10, each provided with a circumferential groove 11, an inner annular flange 12 and an outer and enlarged annular flange 13. Each of these race ways or bearings are provided with one being at each side of the vertical center holes for the passage of'a bolt 14, upon which they are loosely mounted. Each of themes-ways or bearings carries a series of ant1-fr1cti0n balls 15. As shown, these balls bear against the outer flanges13, as well asiv on the grooves 11, and also againstthe inner circumference of the supporting wheel, the outer flange preventingv outward displacement of the balls and confining them in their above stated position relative to the supporting wheel. By reference to the dotted lines, it will be noted that the centers of the balls and the supporting wheel form a pyramid with its base in the longitudinal axis.

In assembling the parts, the balls are placed upon the races or bearings with the inner flanges 12 of the latter abutting and the holes through the bearings alining, the outer flanges 13 then facing the sidepieces 2 of the hanger. The bolt may then be passed through the side pieces of the hanger and the bearings, and by tightening up the nut 16 on the end of the bolt against its head 17, all the parts may be brought together and held firmly in place, the nut and head bearing against the side pieces 2. The bearings may be left just free enough to rotate on the bolt, their lateral displacement being prevented by the side pieces of the hanger. The device, as thus constructed, lends itself to being very readily assembled and taken apart.

I do not limit myse f to tho exact details of construction, but Consider thn my invention is as broad as the scope of th laims appended hereto.
